BAG-HANDLE-ATTACHING DEVICE.

Application filed. September 18, 1922. Serial No. 588,877.

To all :whom it may concern:

Be it known that I, JACOB VANDENBERG, a citizen of the United States, and residing in the town of W oming, county of Hamilton, and State of hio, have invented certain new and useful Improvements in Bag-Handle-Attaching Devices, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to mechanisms for use in the attaching of string handles to that gype of paper bag, known as a shopping In bags of this character I have evolved a method of attaching the string handle by means of gummed tape and a cemented bag fold, which is very strong, and simple, and will outlast the bag, so far asv tearing strings are concerned.

My mechanism which forms the basis of this invention is directed to means for use in the attaching of the string handles according to my method.

The method includes brie-fly the insertion of the string through a-pair of previously formed holes in the side of the bag, said string ends being thrust through from the outside of the bag and permitted to rest on the inner surface thereof. A fold of the open end of the bag is cemented down over the string where it passes through the holes, and a piece of gummed paper tape or its equivalent is pasted down over the ends of the string as they lie on the inner surface of I the bag.

chine, when not in use.

Figure 2 is a like view showing the machine in use,-after the string has been inserted and the clamp swung down.

Figure 3 is a detail of a portion of a bag showing the method of attaching the handle.

Referring first to the bag, I have indicated at l a portion of one side of a bag, which has an inward fold 2 around its upper edge or mouth. Punched out of the body of the bag, on a line to be lapped by this fold are a air of holes 3, 3 for the string handle.

have shown but one side of the bag, but it will be understood that both sides will be similarly formed.

The piece of stout cord or string 4 is bent into a half loop and its ends thrust through the holes 3 from the outside of the bag. The fold is then cemented on several lines adjacent the holes and wiped down over the string and the bag. The ends 5, of the string then lie on the face of the bag,

and a piece of gummed tape 6- is set over the ends, and preferabl also, partially over the fold, and wiped own in place. I have found that a handle so mounted cannot be grasped in the hand and wrenched 01f while holding the closed end of the bag, but that the material of the bag will give way in-. stead. I

Referring now to the invention involved in this application, I have shown a work table 1, on which is mounted a standard 2, carrying a swiveled sleeve 3. The sleeve is formed with an arm 4, having a handle 5, and in the end of the arm is mounted a pressure roller.

This roller is shown at 6, and is mounted in the arm by means of a bifurcated holder 7.

Mounted on the table is a bag holder or spreader shoe, formed of a board 8 having mounting arms 9, 9, which are pivoted or hinged in brackets 10, 10, at the front edge of the table. One of the arms 9 extends forwardly as at 11, where it is connected to a lever 12, operated from a foot treadle. The tre-adle is shown at 13, hinged to a floor plate 14, and pulled by a spring'15 into position to force the shoe to lie flat on the table. A depression of the treadle by the foot will swing the shoe on its hinges to a slanting position above the table.

Mounted on the top of the shoe is a curved bag spreader tongue 16, and beneath the elevated end of the tongue is a heavy presser iron 17, hinged at 18 to the forward edge of the shoe.

It should be noted that the table is formed with grooves 19, 19, therein, which are set to register with the string handle ends, and the presser iron has also like spaced grooves 20, 20. The shoe at its forward edge has for a short distance, (a fraction of an inch) like grooves 21, 21.

s so constructed the device operates as follows: The operator takes a bag, presses the foot treadle and slips the bag over the shoe, at the same time spreading it so as to clear the presser iron. He pulls the bag far enough over the shoe to bring the edge of the mouth thereof about to the edge of the table, and permits the shoe to drop, thereby holding the bag tight, and in an open position.

He then takes a piece of string, cut for a handle, and inserts the ends of the string in the grooves 19 and up through the holes 3, 3", in the bag, forcing the string to the position about as shown in Figure 3. In the preferred form of bag this involves a forcing out of the way of the top fold of the bag and the operator next takes a glue brush and applies it to the top fold, adjacent the string pieces.

He next pulls a piece of gummed tape from a moistening tape holder, and lays it down across the bag, so as to cover the string ends, from the fold to approximately the tips of the said ends.

Next he swings down the presser iron, reaching into the bag with his hand to do so, and swings the arm 4 over the shoe, with the result that the roller presses down on the shoe.

The result of the grooves in the table, and the guiding function of the round holes in the bag, is to force the string to lie in the table grooves, and since the grooves terinmate in the shoe, within a fraction of an inch of its forward edge, this holds the string also, and serves as a guide as to the extent to which the string ends should be forced into the bag. The grooves in the presser iron register with the table grooves, and thus the result of pressing down on the iron is to wipe the tape and the material of the bag closely around the string ends, thereby completely housing the string between the bag and the tape, and providing a ermanent string end retaining means.

he entire operation can be done very quickly with the mechanism now described, and when finished, the shoe is elevated, the bag drawn off, and then reversed and the other side treated in a like manner. In practice it is found to be better to attach handles to one side of a batch of bags, and

a table having interspaced grooves to reg-' ister with the ends of a string handle, a

bag expanding shoe mounted on the table and adapted to hold a bag with interspaced holes in said bag in registry with said grooves, and a presser device adapted to a ply pressure against the inner surface of th e bag.

In a device of the character described, a table having interspaced grooves to register with the ends of a string handle, a bag expanding shoe mounted on the table and adapted to hold a bag with interspaced holes in said bag in registry with said grooves, and a presser device adapted to apply pressure against the inner surface of the bag, said presser device also having grooves therein to register with the grooves in the table.

3. In a device of the character described, a table having interspaced grooves to register with the ends of a string handle, a bag expanding shoe mounted on the table and adapted to hold a bag with interspaced holes in said bag in registry with said grooves,
